F1	As previously reported in a Form 4 filed by the Reporting Person on February 25, 2022 (the "Original Form 4"), shares of Amkor Technology, Inc. (the "Issuer") common stock underlying time-vested restricted stock units (the "2022 RSUs") were granted to the Reporting Person on February 24, 2022. In the Original Form 4, the 2022 RSUs were incorrectly reported in Table I. Table II, Column 9 of this Form 4 has been adjusted to include the 2022 RSUs and reflects the proper number of 2022 RSUs beneficially owned by the Reporting Person as of the filing date of this Form 4.
F2	As previously reported in a Form 3 filed by the Reporting Person on October 12, 2021 (the "Form 3"), shares of the Issuer's common stock underlying time-vested restricted stock units (the "2021 RSUs") were granted to the Reporting Person on February 11, 2021. In the Form 3 and in subsequent Form 4s filed by the Reporting Person, the 2021 RSUs were incorrectly reported in Table I. Table II, Column 9 of this Form 4 has been adjusted to include the 2021 RSUs and reflects the proper number of 2021 RSUs beneficially owned by the Reporting Person as of the filing date of this Form 4.
